The Soviet Union played the leading role in fish introductions in Eurasia. However, only 3% of all introductions prior to 1978 gave a commercial benefit. One of the noteworthy examples appears to be the Sevan trout (Salmo ischchan Kessler, 1877)-an endemic salmonid of Lake Sevan in Armenia. This species has been introduced to Kirghizstan, Kazakhstan, and Uzbekistan, however, only the Kirghiz po...

In order to increase the size of declining salmonid populations, supplementation programmes intentionally release fish raised in hatcheries into the wild. Because hatchery-born fish often have lower fitness than wild-born fish, estimating rates of gene flow from hatcheries into wild populations is essential for predicting the fitness cost to wild populations. Steelhead trout (Oncorhynchus mykis...

An investigation was carried out based on the survey of the problems and prospects of fish fry trade in Jessore district in Bangladesh. The survey was conducted on 82 nursery operators and 50 fry traders from different parts of the country. The objective of the study was to know the present status of the trade, identify the problems associated with the business, assessment of aids needed for th...

To determine the effect of development and environment on fin growth, we measured fin lengths of juvenile Atlantic salmon (Salmo salar) from two hatcheries (August, October and April–May), stream-reared fish (July and October) stocked as fry into two tributaries, and smolts from the main stem of the Connecticut River (May). For stream-reared parr, there was a linear relationship between the dor...

Indonesia has a high potential for pearl oyster farming due to its diverse marine habitats, warm waters, and abundant supply of seaweed, which is the preferred food oysters. home several species oysters, including Pinctada maxima, are prized their large size quality pearls. Water plays crucial role in cultivation maxima. Factors such as temperature, pH, salinity, dissolved oxygen levels, presen...

BACKGROUND:The bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. OBJECTIVES:The aim of this research was to investigate the bacterialcontamination status, with emphasis on Escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated Escherichia coli. METHODS:Ato...

As the start of supply chain for aquaculture industry, hatcheries are a crucial component in success oyster and northern quahog (hard clam) on East Coast USA. Intermittent failures hatchery production slow industry growth reduce profits. To begin investigations into possible role algal toxins failure, post-treatment water from one research four commercial lower Chesapeake Bay, USA, was sampled ...
